目前,抽象含义表示 (AMR) 注释中尚未捕获许多英语时态和体语义对比。所提出的框架增强了 AMR 中有限谓词的表示,包括四向时间区别(语音时间之前、之前、之时或之后的事件时间)和几个方面的区别(包括静态与动态、习惯性与情景性以及目的性与无目的性)。我们通过对《小王子》中的句子进行小型注释研究来验证这种方法,并报告正在进行的讨论的细节以完善框架。这将使 AMR 能够用于需要对时间和事件结构进行复杂推理的 NLP 任务和应用程序。
Many English tense and aspect semantic contrasts are not currently captured within Abstract Meaning Representation (AMR) annota-tions. The proposed framework augments the representation of finite predications in AMR to include a four-way temporal distinction (event time before, up to, at, or after speech time) and several aspectual distinctions (including static vs. dynamic, habitual vs. episodic, and telic vs. atelic). We validate this approach with a small annotation study of sentences from The Little Prince and report details of ongoing dis-cussion to refine the framework. This will en-able AMR to be used for NLP tasks and applications that require sophisticated reasoning about time and event structure.
